POWER-TRANSMlSSION ATTACHMENT FOR .AUTOMBILES To all zii/.nini 'it muyconcern.'

Be it ltnoivn that. Tiioiiixs Nason. of lndianapolis, county of Marion,and Slate o't' Indiana, have invented a certain usefulPower-Transinission Attaeliiiieiit for A utoY mobiles; and l do herebydeclare that the llw-ilowingij is a full, clear, and exact descriptionthereol, reterence being had to the accompanying drawings,

, The object of this invention is to provide suitable niechanisn'i to beused in combinar tion with an automobile for the purpose'o'ltransmitting power from the automobile to other machinery. Thus. a.farmer, by n'ieans oi: this invention, could use his4 initoniobile todrive various agricultural machines and devices7 particular-lj when itis desired to run thein tor only a vshort time, such as a cider niill,corn Sheller, wood san', and the like. Incidentally the device inav beused also tor liitingr the rear autoiuoliiile Wheels ott the ground, sothat it may be run loneI enough to gettlie ei'in'ine vwell started.

The nature of the invention Will be understood 'trom the aeeonipanyinn`drawings and the followingA description and claims.

ln the drawings Figure 1 is a plan view of said device combined with therear part oi the elias-sisot/an automobile, vthe driving' belt ol saiddevice being partly broken away. Fig. 2 is a section on the line Qwff ofFig. 1. Fig. l is a modified torni ot Fig. Fin'. ll is a. section on theline 4 4 ot Fig'. 1 on a larii'cr scale. Fig. .1 is a section on theline :1Mo ot Fie'. l.r but on a larger scale, VFig'. (S shows auioditicd torni oi2 the lever shown in Fips. 1 and There is shown therear tubular axle 10 otau automobile and the rear Wheels 11 thereoicdriven by the shat't 14 and other means inelosed in the tubular axle andthe parts 1i. and 13A, which7 however, is rnot entirely illustrated. Sotar as this invention is concerned. it is immaterial how the wheels otthe automobile are driven, or

' which wheels. Whether front or rear7 as the device may be applied toei-tlier'the front or rear wheels.

A `traine7 the length of which is substan tially equal to the width oilthe automobile` provided, and it is triangular in cross.

section7 consisting o end portions having a bottom horizontal part 15, avertical part 1G 4'at the rear, and an inclined brace portion '17. 'lhetwo triangular portions at each end are connected by cross rods 18,Altliand 20 for Specification of Letters Patent-- 13315931343@Sep/5.241%, 1912" Appiicanon inea February e, i911.

spacing tliein and holding1 thein upright'. They are arranged so thatthe traine as a whole can he put in place between the rear wheels of anautomobile and the triangular ends ot' the traine will be near theWheels. An upward projection 120 extends from each triangular end etsaid 'trarne and is provided with a nun'iber of holes 2l through which apin 22 tor ft'ilcruining the lever E?! may be inserted. rThere is alever at. each end ot the traine and the inner end of each lever isformed so as to engage the underside of theaile 10 near the Wheel andsupport and litt said axle. The elevation of the lever 23 can beadjusted by reisen of the holes 21 to suit axles ot verying elevations.`

From each triangular end traine near the top, there is a rearwardlyextending tube or rod and on each rod there is a sliding sleeve 2Gcarrying a siviveled bearing 27 for the shaft QS which extends from onerod Q5 to the other and carries a pulley 29 tor a vbelt 129, wherebyiibiv'er. can be transmitted to any ot her machine or device. There isinounted on eachend of said shaft 2S a frie-- "tion wheel 30" with. aconcave peripheryy adapted. to engage the convex periphery of theadjacent rear automobile wheels and be actuated thereby. The peripheryof the friction wheels are provided With' transverse corrng'ations 3l togive the rubber of 'the automobile Wheels a better grip, or to .increasethe eoeiiicient of friction between the wheels 11 and 80. The frictionwheels 30'are held snugly against the tires of the automobile tractionWheels l1 by springs-32 surrounding the rods or tubes 25, and thetension thereof is adjusted by the nuts on the threaded portions oftherod Then the device is put in place` behind an automobile, the levers 23are actuated for lifting the aide of the automobile by removable bars35. These may be straight bars of iron fulcrumed on flanges 3G on theinner surfaces 'of the rear ends of tie levers Q3, and the stront endsof the bars 3 catch under projections 3? near the upper edges ot thelevers 23 between the nloruins 36 and the -pivot pin 22. This enablesthe bars to be used and the leverage increased. When the automobile axleis elevated. so the Wheels are ed the groui'ida the rear ends oi? thelevers 23 are held down for holding the Wheels and axles elevated bybrackets l0 which loosely surround the rods 25 ad have an oveihhangine|-threaded portion el,

upper end or" the screws ,1, its

shown in Fig, 2, through which a screw extends which enters groove i3longitudinally in the upper surface of the rear portion of the levers23. When the device is taken away tron-'1 the automobile, tlf-e screws42 are released and the brackets 40 will turn on the rods 25.

The modified torni is shown in Figg where a hooked portion dit oi" thebracket- Il() engages a slot or recess 45 in the lever The idle positionot the bracket 4.0 is indi v.

cated by the dotted lines in Fig. 3. There is also shown in Fig. anordinary hooked hracliet 'l5 loosely placed onrthe rod .25 so that itcan be turned up and caught over the lever 23, it' desired.

use the power transmission device is placed at the rear end ot theautomobile and the levers inserted under the axle, and the automobileand axle are lifted until the wheels are ottn the ground, and the levers23 are held in suoli. position by the brackets #il- O The nuts aretivlitened up so as to bring the triction wheels 30 against ,the rubbertire oit the automobile wheels,

and the automobile engine is started, and power is transmitted throughthe belt 129 in the device which is to be driven. It it desired to driveonly one friction wheel 30, the swiveled bearing Q7 will enable theshaft :Brte be adjusted so that only one friction yi'vheel will touchthe rear wheels ot the automobile It it be desired only to run theautomobile engine a while to get it heated and well under 'way beforestarting` the automobile, the device performs the of a jack. ln thatinstance the ic- 'tion wheels 30 need not be brought in touch with theautomobile wheels.

in Fig. 6 modified torni of the lever Q3 is shown, with. two bosses and5l on the sides through which two screws and 53 entend. A wooden blocksecured to the and in position to receive the shaft 14. By means of thescrews the blockA may be elevated to center the shaft ILO in relation tothe shaft l claim as my invention:
